针对当前综合能源可靠性评估方法大多是面向微网系统,难以从系统拓扑结构角度分析区域综合能源系统可靠性的问题,建立了一种基于复杂网络理论的区域综合能源系统可靠性评估方法。首先,以区域综合能源系统作为研究对象,介绍了区域综合能源系统的基本结构,并分析了复杂网络理论应用的可行性;其次,通过对复杂网络内距离参数的改进,构建了包含网络特性的加权复杂网络模型;在此基础上,从系统网络拓扑的角度提出了包含节点以及系统整体的可靠性评估指标。最后,通过构建实际测试算例,验证了方法的有效性与适用性。文章探索了复杂网络理论在区域综合能源系统可靠性评估中的应用,可为未来区域综合能源系统的规划建设提供可靠性层面的指导。

In view of the fact that most of the current assessment methods for integrated energy reliability are oriented to microgrid systems,it is difficult to analyze the reliability of regional integrated energy systems from the perspective of system topology.A method for evaluating the reliability of regional integrated energy systems applying complex network theory is established.Firstly,taking regional integrated energy system as the research object,basic structure of the regional integrated energy system is introduced and the feasibility of the application of complex network theory is analyzed.Secondly,by improving the distance parameters within the complex network,a weighted complex network model including network characteristic is constructed.On this basis,from the perspective of system network topology,reliability evaluation indices including nodes and the system as a whole are proposed.Finally,the validity and applicability of the method are verified by constructing actual test cases.This paper explores the application of complex network theory in reliability assessment of regional integrated energy systems,and provides guidance on the reliability level for future planning and construction of regional integrated energy systems.
